Hi this is the first grow ive ever attempted!! I bought 5 feminised cheese seeds from greenhouse seeds but only decided to germ 1 incase any major problems occured it wouldnt be a total waste. Conditions =

Indoor Tent 80cmx80cm 160cm tall.
400w grolux dual spectrum cooltube about 97 cm from plant top.
No extraction fitted yet but will have one next week atm just using a clip on fan pointing at light, pushing air through top of zip flap! Natural intake through bottom vents.
Temp Day 24-27 deg celcius--Night 16-19
Humidity aprox 25-35%

Im growing using Passive Hydroponics with=
Grodan Rockwool seed, transplant and growing cubes.
Canna Nutrients=
Rhizotonic for seedling 4ml per litre NPK= 0,6-0,2-0,6
Canna Hydro Vega A+B Hard Water. 1ml per litre NPK= 6 - 2 - 8.
I water 1-2 times daily with little run off or when pot feels light
Im using Hard tap water ph around 7.0+ after nutrients ph rounded off to 5.5-5.8

So as you can see in the pictures the leaves are loosing colour with white patches appearing on older leaves, same thing happened with first true set of leaves which no longer exist.
At first i thought it might have been spider mite so sprayed with SMC twice over a week but a week later second set are facing the same fate!

Next week i'll be getting a new 125mm extractor fan, Cannazym, Canna Nitric Acid PH Down and Hesi super vit.
Untill then any recomendations or help will be greatly appretiated

If you need further info on nutrients or anything else please ask i will answer any questions as best i can Thanks ppl :rastasmoke:
